ViewPager in ScrollView won't scroll vertically

I have a layout that has a `ViewPager` inside of a custom `ScrollView` and the ViewPager won't scroll vertically. The custom ScrollView is used to fix the dreaded tab swiping with a ScrollView. Yes, there is enough content for it to scroll and I've tried with and without the bottom buttons. I'm using the ActionBar that has 3 tabs and the current code allows swiping left / right just fine. My goal is to have the bottom bar for a couple action items such as save and cancel and the part between the ActionBar and the buttons at the bottom be the ViewPager that will scroll vertically. I've tried too many combinations and am now sending this love letter to you. Any ideas? Any help is appreciated and feel free to ask for additional details if needed. main.xml ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:id="@+id/footer" style="@android:style/Holo.ButtonBar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:orientation="horizontal" > <Button android:id="@+id/saveButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="Save" /> <Button android:id="@+id/cancelButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="Cancel" /> </LinearLayout> <com.blah.hootiehoo.ViewPagerCompatScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_above="@id/footer" android:fillViewport="true" > <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:scrollbarAlwaysDrawVerticalTrack="true" android:scrollbars="vertical" > <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:scrollbarAlwaysDrawVerticalTrack="true" android:scrollbars="vertical" > </android.support.v4.view.ViewPager> </LinearLayout> </com.blah.hootiehoo.ViewPagerCompatScrollView> </RelativeLayout> ``` MainActivity.java ``` ViewPager mViewPager; TabsAdapter mTabsAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mViewPager = (ViewPager)findViewById(R.id.pager); // setup action bar for tabs ActionBar actionBar = getActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); actionBar.setDisplayShowTitleEnabled(true); actionBar.setDisplayHomeAsUpEnabled(true); mTabsAdapter = new TabsAdapter(this, mViewPager); Tab tab = actionBar.newTab(); // tab setup mTabsAdapter.addTab(/*** stuff ***/); // add 2 more tabs, etc } ``` ViewPagerCompatScrollView.java Got from here, at bottom ``` public class ViewPagerCompatScrollView extends ScrollView { private float xDistance, yDistance, lastX, lastY; public ViewPagerCompatScrollView(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: xDistance = yDistance = 0f; lastX = ev.getX(); lastY = ev.getY(); break; case MotionEvent.ACTION_MOVE: final float curX = ev.getX(); final float curY = ev.getY(); xDistance += Math.abs(curX - lastX); yDistance += Math.abs(curY - lastY); lastX = curX; lastY = curY; if(xDistance > yDistance) return false; } return super.onInterceptTouchEvent(ev); } } ```
